The DCB612 is DEWALT's highest-capacity FLEXVOLT battery at 12.0Ah, automatically switching between 60V MAX and 20V MAX tools. At 12.0Ah in 20V mode (4.0Ah at 60V), it delivers up to 8X the runtime of the standard 1.5Ah 20V MAX pack in 20V MAX* applications. The DCB612 uses the same physical form factor as the DCB609 9Ah, making it a drop-in upgrade for any FLEXVOLT tool kit. Compatible with 20V MAX*, 60V MAX*, and 120V MAX* FLEXVOLT systems. It is DEWALT's heaviest-duty cordless battery, designed for all-day runtime on demanding 60V MAX tools. Covered by DEWALT's 3-year limited battery warranty.
How does the DCB612 12Ah compare to the DCB609 9Ah?
The DCB612 provides 33% more capacity than the DCB609 in the same physical form factor. Reviewers who upgraded from the 9Ah to the 12Ah note a meaningful increase in all-day runtime on demanding 60V MAX tools like miter saws and chainsaw. Both are compatible with the same tool lineup.
Is the DCB612 compatible with 120V MAX FLEXVOLT tools?
Yes. When two DCB612 batteries are used together in 120V MAX FLEXVOLT tools, they deliver combined power for the most demanding cordless applications, such as the DEWALT FLEXVOLT 120V MAX circular saw and reciprocating saw.
How long does the DCB612 charge take?
With the DEWALT DCB1106 6-amp fast charger, the DCB612 charges in approximately 90 minutes. The DCB115 1-amp charger will take significantly longer. DEWALT recommends the fast charger for the most efficient workflow with high-capacity FLEXVOLT batteries.
Can I use the DCB612 in my 20V MAX cordless drill?
Yes. In 20V MAX tools, the DCB612 delivers 12.0Ah capacity, providing exceptional runtime on drills, impact drivers, and other standard 20V tools. The battery automatically switches to 60V mode when installed in a FLEXVOLT tool.
Is the DCB612 heavier than the DCB609?
The DCB612 and DCB609 share the same physical form factor and similar weight. Both weigh approximately 3.5 lbs. The additional capacity in the DCB612 comes from higher-density cell packaging within the same housing, not from a larger case.
